(Cl. 1D0-8) 2 Claims. l

My invention refers to baling presses for paper, rags, leather, rubber, etc. and it has for its object to provide a simple, durable and economically constructed press, having all of the advantages of the more expensive standard type while at the same time a material saving in space and bulk is accomplished both as to the height and body area of the same.

Specific objects of my invention are:

To provide means for filling the box from the top.

To provide a platen having a centrally disposed receiving or loading opening therein with a hinged closure therefor and manually controlled lock and release means.

To provide sliding doors for controlling the bale ejection side openings of the box, whereby economy in lateral space is obtained and pressure strain is uniformly resisted.

With the above and other minor objects in view, my invention consists `in certain peculiarities of construction and combination of parts as will be fully set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings:

Figure 1 represents a side elevation of a baling press embodying the features of my invention with parts broken away and in section to more clearly illustrate structural features, the section being generally indicated by line I-I of Figure 3.

Figure 2 a top plan view of the same with parts broken away and in section to more clearly illus'- trate details of construction with a special reference to the toggle link platen actuating mechyanism.

Figure 3 a longitudinal sectional elevation through the press as indicated by line 3-3 of Figure 1.

Figure 4 an enlarged fragmentary sectional elevation showing one form of the lock and release mechanism for the baling press ejection doors, the section being indicated by line 4-4 of Figure 2.

Figure 5 a sectional plan view of the same, the section being indicated by line 5-5 of Figure 4.

Figure 6 an enlarged fragmentary plan view of the spring controlled panel closure latch means; and

Figure 7 a detail plan View, partly in section, of my preferred form of door for the bale ejection openings of the box.

Referring by characters to the drawings, I indicates the end walls of the box and 2 the side.

2 walls of the same forming, in conjunction, with the walls I, bale ejection openings. These openings are provided with closure doors 3 hinged'to the side walls. The doors when closed, in e'ect, form the sides of the baling box and, in this instance, each of them is locked by means of pairs of apertured lugs 4 secured to the end walls I, as best shown in Figures 1 and 4 of the drawings. These lugs are engaged by apertured ears 4 which extend from the free ends of the doors. When the doors are closed they are locked to the end Walls by pins extending from a rod 5 whichv is reciprocatively mounted in lugs 6 that extend inwardly from the box side walls 2. When it is desired to unlock the swinging doors, a foot pedal 1, pivoted to the bottom of the press and extending outwardly therefrom, is manipulated to lift the rods, it being understood that said rods Vin their locked positions may move downwardly through their weight or through spring pressure.

The top portion of the press box has secured thereto a rectangular housing shaving a filling opening 9" therein communicating with the baling press box, and reciprocatively mounted in the box is a skeleton press platen IIJ in angle iron form. The vertical flanges of the angle iron form a press platen filling opening II, which filling opening is closed by a centrally disposed panel I2 which panel, in effect, constitutes a part of the platen. Y

As best shown in Figures 2 and 3 of the drawings, the panel is connected to the vertical flange II of the platen by hinges I3, it beingunderstood that the platen and associated panel are provided with the usual spaced slats, as is also the bottom of the press box, for convenience in baling.

The housing 8, at its ends, has journaled therein a pair of threaded rods I4 aligned over the angle iron edges of the platen IU which is provided with ears for pivotal connection to pairs of links I5, the opposite ends of which are pivoted to nuts I6, which nuts are slotted at their upper edges for sliding engagement with strips I'I that extend downwardly from the housing wall, as best shown in Figure 3 of the drawings, the nuts being in threaded union with the threaded rods I4, whereby said nuts are held against turning when they move back and forth upon the rods which are rotatable.

From the foregoing description, it will be noted that a comparatively shallow housing 8 is mounted above the press box I and it carries not only the reciprocative platen but all actuating mechanism for the platen. Hence, said housing and pulleys are in belt connection with pulleys |95 mounted on a stud shaft 2D, that is journaled in an end wall 2| forming part of a chamber A extending from the end walls Iiof: the baling press box, it being understood that the companion chamber A at the opposite end of the press serves` as a housing for the swinging doors locking mechanisrn.

Thewall' 2| associated withtthe drivingmechani'sm of thel threaded. rodshas secured` thereto: an offset casingf2f2', which-.casing has mounted' therein; upon the baling' box. door, an' electric motor 23E The electric motor, under suitable control, imparts' driving.: power't'o thethreadedA rods M by-meansof a pulleyand beltconnection B. The spring`v controlled latch; which` locks the hinged panel portion ofV the.platen,.comprises a flanged plunger' 245" slidable in track. railsA 25l secured to the bed` of theipanelv |12; The rear end of. the

plunger is provided with` a'y socket into which al coil spring 2B is fitted; the oppositev end` of the latter. beingu in engagement` with. the; flangel web Hf, which is provided with an spring retaining tongue Ill-f, as best show-ni in Figure 6 off the; drawings: The frontendoft'he plungerfis'tapered' andlocks 7under a' oorrespondingitapered tooth` 2.1.

The top face offthe latch plunger 24'has secured thereto a vertically' extended handle 28Y which projects; theV feed opening 910i the. housingVV 8; to permit fl'e'eaccess` thereto, ast-indicated in Figures 1 and;Y 3 fofthe drawings.-

In the operation. of: the baler, when it is de.- sired tov chargey the same.- withA theA product to beA bal'ed.; the latch handle.v 28 ist moved backward (as: indicated: in dotted'y lines in Figure 3). The

latolihandle is then utilized to swing open theA panel to the position indicated in dotted. lines, Figure 3,'.tl'1us clearing thev lling opening in.l the platen, whereby thef material is freely fed into thebox. The panel lr2-is tlien swungl back. tothe positionishown'inull llnes,.Figure 3, whereby the platen; is closed throughout its surface, due to thef spring. controlled: latch snapping into its locked position.

@wing tothefact that the panel I2 is hinged, imthe eventthe material forbaling should mound, itvma-'yreadily bepressed downward: for closure, without snarlingzor-clogging atl its edges.

It is further emphasized that the actuating setsio toggle links IE/ are positioned.y under and beyond .the sides of thelling,y opening4 ofthe housing; whereby'saidlinksandiother actuating mechanism: areY protected, as said parts arev` all beyond thesidesofthehousing=1lingopening.

In order tocomplete the baling operation, the motor isstarted, to impart rotation to the threaded rods, whereby the nuts, now in the position showininlFigure. 1, will spread apartand-thelinks l; inspreading, will-cause theV platen l0. tol move downwardly to its limit position, indicated in dotted lines, Figure 1, whereby complete compression of the product is effected. Thereafter the doors, closing the bale ejecting openings, are moved from their locked positions clear of said openings. The compressed bale is then confined by cords or runners in the usual manner and said bale is then ejected. The motor is thereafter startedin reverse to move the platen upwardly tothe position-shown in Figure'l. Thus it will be seen that alll of the mechanism is self contained within the area of the baling press.

While I have shown and described the press doors 3 fully as to detail, it should be understood in practice I prefer to utilize sliding doors such as illustratedin Figure 7 of the drawings, which slidingdoors are particularly advantageous, due to the fact that they may be opened and closed within the confines of the side walls of said baler. As will be seen in Figure 7, the door 3 is slidable in channel' strip's- 29 carried by the baler side walls. 2.

While I have shownandfdescribed.oneformof my invention specifically as to-detail, it'isundersto'od` that I mayl varyv the structural features withinthescope of the claims.
